Science
Mechanism of Action
Lysine Hyaluronate functions through a unique structural design where an amide bond formed between hyaluronic acid and lysine effectively conceals the hyaluronidase recognition site. This engineered resistance significantly reduces enzymatic breakdown, extending the molecule's residence time and therapeutic impact in the skin. Beyond stability, this cross-linking actively drives the synthesis of critical type 1 and type 3 collagen, essential for maintaining skin structure and elasticity. Concurrently, the intrinsic benefits of lysine contribute to calming inflammation, regulating oil production, supporting the healing of post-inflammatory marks, and fortifying the skin's natural barrier, all while ensuring optimal moisture levels for cellular regeneration and tissue repair.

Key findings
- 01 In a double-blind randomized controlled trial for decubitus ulcers, Lysine Hyaluronate demonstrated markedly superior ulcer reduction and faster healing compared to standard sodium hyaluronate. For stage 1 ulcers, a 90% lesion size reduction was observed with Lysine Hyaluronate, versus 70% with sodium hyaluronate. In stage 2 and 3 ulcers, reductions were 70% and 71% respectively for Lysine Hyaluronate, significantly outperforming sodium hyaluronate's 40% and 29%.
- 02 An amino acid cross-linked hyaluronic acid, effectively Lysine Hyaluronate, designed as a dermal filler, positively influenced the expression of type 1 and type 3 collagen in epithelial tissue in a mouse model, showing higher expression rates compared to Restylane.

Dusting Analysis
The robust clinical evidence demonstrating superior wound healing and collagen-boosting capabilities compared to conventional sodium hyaluronate suggests that Lysine Hyaluronate offers genuine, measurable benefits, indicating it is unlikely to be merely a 'dusting' ingredient.
The Formula
Formulation
Stability
The cross-linking of hyaluronic acid with lysine creates an amide bond, which shields the hyaluronidase recognition site, thereby enhancing the ingredient's stability against enzymatic degradation and prolonging its residence time in formulations. Multilayer films containing poly(L-lysine) and hyaluronic acid have shown stability across a wide pH range of 2.5 to 11.5.

Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has concluded that related forms like Hyaluronic Acid, Potassium Hyaluronate, and Sodium Hyaluronate are safe in cosmetics at concentrations up to 2%, and lysine is an essential amino acid, Lysine Hyaluronate itself has not yet been formally reviewed by the CIR Expert Panel.
